  • Patent number: 11266387
    Abstract: A medical system includes a flexible catheter, an imaging probe, a working catheter, and a positioning system. The flexible catheter includes a plurality of first lumens and a sealing device having one or more balloons to seal the anatomic passageways at a sealing location and one or more flaps or valves to remove air from the anatomic passageways. The imaging probe and working catheter are receivable within the plurality of first lumens and extend through the sealing device. The working catheter includes one or more second lumens to receive a medical instrument. The positioning system is configured to determine a position of a distal portion of the flexible catheter, the imaging probe, or the working catheter. The medical system is configured to collapse a portion of the anatomic passageways distal of the sealing location by removing air from the anatomic passageways to facilitate ultrasound imaging using the imaging probe.

  • Publication number: 20200148767
    Abstract: Anti-CD33 antibodies are described. The anti-CD33 antibodies can bind within the V-set Ig-like domain or the C2-set Ig-like domain of CD33. Epitopes on the C2-set Ig-like domain can provide a “pan-binding” site, to which the cognate antibody will bind regardless of whether the CD33 molecule also contains the V-set domain (as in, for example, CD33FL) or not (as in, for example, CD33?E2). Alternative epitopes on the C2-set Ig-like domain are accessible for binding if the V-set domain is absent (e.g., as in CD33?E2). Antibodies that bind an epitope on the C2-set Ig-like domain (whether they exhibit pan or V-set absent binding) are directed at novel therapeutic targets and can increase therapeutic efficacy against CD33-related disorders. Also described are molecules comprising a binding-competent domain from at least one described anti-CD33 antibody, including scFvs, bi-specific antibody molecules, chimeric antigen receptors, and immunoconjugates. Methods of use are also provided.

  • Patent number: 10460253
    Abstract: A method for solving the NP complete problem 3SAT and other computational problems which can be reduced to it. Quantum mechanical operations are performed on a finite number of quantum mechanical bits, or “qubits,” in such a way as to concentrate probability in states which solve a given 3SAT problem, provided they exist. Concentration of probability is achieved by generalizing the traditional, reversible model of quantum computation to include irreversible operations mapping one density matrix to another.

  • Publication number: 20190233534
    Abstract: Groups of bi-specific binding domain constructs (BS-BDC) to treat cancer are described. Each BS-BDC in a group targets a cancer antigen epitope and an immune cell activating epitope that is different from the cancer antigen epitope and immune cell activating epitope targeted by another BS-BDC in the group. The different cancer antigen epitopes can be on the same cancer antigen.
